Yes, this game is quite similar to JezzBall, or to a more modern example, Just Fillin’, which used to be available on the iPhone. I remember playing JezzBall back in the day on a floppy disk, and Just Fillin’ during the early days of the iPod Touch. It’s no longer available, but when I mentioned it, my 11-year-old son tried to recreate it, and honestly, I think he did a pretty great job.
This is so nostalgic. I remember feeling like I was so good at Jezzball. In later levels I'd start a wall near one corner of the screen, closer to one edge than the opposite edge, to ensure the shorter wall would connect, and sacrificing the longer wall. The surviving wall would create a "corridor" in which to trap balls with tiny horizontal walls, often such that they ended up completely stationary.
